Review Summary

I am requesting changes because there is a checklist violation that can affect the correctness of your submission, even though the core CRUD functionality works well. Your ActorManager correctly implements create, all, update, and delete, uses Actor as a dataclass, and creates the SQLite connection in __init__, so the main functional requirements are met. However, the checklist explicitly states that if a database contains more than one object, the table name must be plural [CHECKLIST ITEM #4]. In your current design, table_name is accepted freely (e.g., "actor"), with no enforcement or documentation that it should be plural like "actors", which makes it easy to violate the checklist.

To fix this, at minimum clearly document in ActorManager.__init__ that table_name must be plural, or better, add a small guard that checks the name and either raises a helpful error or adjusts it to a plural form. In addition, your managers.py file currently fails flake8 due to missing return type annotations, too many blank lines, and one overlong line; while these are mostly style issues, you should address them so automated checks pass cleanly. Once you enforce or document plural table naming and resolve the lint errors, your solution will fully satisfy the task requirements and checklist. Overall, you’re very close; the functionality looks solid, and these changes will bring it in line with the expected conventions.

This line can violate checklist item #4: If db contains not only one object - name it plural. Since table_name is passed in freely, it’s easy to use a singular name like "actor", which would contradict the checklist. Consider enforcing or clearly documenting a plural table name such as "actors".

Review Summary

I am approving your solution because it satisfies all core functional and structural requirements: Actor is a proper dataclass in models.py, ActorManager is implemented in managers.py, the database connection is created in __init__, and all CRUD methods work correctly on the configured table and return the expected types (including an empty list from all() when there are no rows). Class and default table naming follow the checklist expectations: the manager name is singular and the default table name "actors" is plural.

There are no critical blockers: nothing breaks functionality, and all required features appear to be implemented correctly. One area you could still improve (not required for this approval) is to more clearly enforce or document that table_name should be plural—either via a short docstring note on ActorManager.__init__ or a simple runtime check that warns when a singular name is passed [CHECKLIST ITEM #2]. You could also tighten the return type of all() from Any to list[Actor] to help static analysis and readability. Overall, you’ve built a clean, working implementation that aligns well with the task and checklist; nice job.
